Abstract

According to 2020–2022 development strategy, Stoilensky GOK is going to increase production capacities from 38 Mt/yr in 2020 to 42 Mt/yr in 2022 (at the initial design capacity of 12 Mt/yr). Stoilensky GOK can reach this objective by force of modernization, machine capacity increase, enhancement of technical preparedness factor and use factor of equipment, as well as by improvement of ore crushing and milling technology using crushers KKD-1500/180 coupled with large diameter mills MSHTS 5800×6500. A promising ways of raising performance and reliability of milling equipment is introduction of digital prediction analysis systems. In 2020 Stoilensky GOK jointly with Uralmashplant undertook technical audit of mills MSHTS 5500×6500 toward:
– assessment of current status and yield safety factor of mills at Stoilensky GOK concentrating plant for the further expert evaluation and finite element-based analysis (in ANSYS);
– development of milling equipment maintenance program (reconditioning repair and replacement) at Stoilensky GOK;
– recommendations on improvement of reliability and capacity of milling equipment at Stoilensky GOK concentrating plant.
Based on the technical audit results, it is recommended to replace some mills in use, in the fixed periods from the FEM-based analysis (within 5 years), by the other milling equipment (manufactured by Uralmashplant) of higher capacity and reliability based on advanced engineering solutions.
